Card Installation and Node Startup 3-31
Making Frame Relay Connections
Step 5 For optional Y-cable redundancy, configure the two cards by using the addyred
command. For Y-cable redundancy on a HSSI card, you must use port 1 of the cards for
the primaryand redundant ports.For importantinformation about Y-cable redundancyon
a UFM-U, see the description in the UFM-U portion of the Cisco IGX 8400 Series
Reference.
Step 6 Activate the ports using the upfrport command.
Step 7 Configure theport for DCEor DTE mode,speed, clocking, LMItype, and soon, byusing
the cnffrport command. Alternatively, you can keep the default parameters. If you plan
to bundle connections, use cnffrport to set the Port ID to the DLCI planned for the
near-end connections beforeyou add the bundled connections.The PortID is optionalfor
non-bundled connections. Note that cnfport functions the same for Frame Relay as
cnffrport.
Step 8 Add connections by using the addcon command. Adding connections requires the slot
number, logical port number, and DLCI for each end of the connection. Frame Relay is a
purchased option. If you attempt to add connections but the system display states that
Frame Relay is not available, call the TAC through Customer Engineering.
If you do not know the Frame Relay class intended for entry with the addcon command,
determine which FrameRelay class numberto use. Use theDisplay Frame Relay Classes
(dspfrcls)command tosee theparameters thateach classspecifies. Tomodify parameters
in a class, use Configure Frame Relay Class (cnffrcls).
Step 9 Optionally—for an individual connection—you can configure bandwidth parameters or
enable ForeSight (if purchased) by using Configure Frame Relay Connection (cnffrcon).
Optionally, you can set the channel priority by using the cnfchpri command. Normally, the
system-default priority is adequate.
Commands for T1/E1 Frame Relay
To specify logical ports on a T1 or E1 interface, use addfrport. The addfrport command assigns a
logical port number to a physical line and a range of 1 or more DS0s/timeslots. Use the logical port
number toactivatea port (upfrport),add connections (addcon), ordisplay statistics(dspportstats).
For example, after you add logical port 14.60 2.1-24 with addfrport, you up this logical port by
entering “upfrport 14.60.” The maximum number of logical port numbers on a UFM-C is 250. Use
dspfrport to display logical ports.
Deleting a Frame Relay Port
Delete a logical port by executing the delfrport command. Executing delfrport dissolves any
groups ofDS0s/timeslots andunassigns allDS0s/timeslotson thelogical port.(Note that,before you
delete a Frame Relay port, you must delete any connections on the port with delcon.) After deleting
a logical port with delfrport, you can de-activate the physical port with dnport.
Setting Up Frame Relay on an FRM
Four types of interfaces are available for the FRM. The back cards have the following terminations:
• The FRI-T1 has a female, subminiature DB-15.
• The FRI-E1 hasa single 120-ohm,DB-15 connector for abalanced termination andtwo, 75-ohm
BNC connectors for coaxial cables for an unbalanced termination. All connectors are female.
• FRI-V.35 has standard 34-pin female MRAC type connectors with a standard V.35 cable.
